http://mythtv.org/wiki/index.php/Overscan#.22Why_doesn.27t_the_desktop.2FMythTV_interface_fit_properly_on_my_TV_screen.3F.22
This may be of interest to you,However I have a 56" Samsung which uses the VGA connector and I have the damn over scan for the desktop, which I cant fix at all it seems, use another MD to count the up down left right clicks, to configure mythtv settings since you cant see them on the screen....its a pain!

I'm not sure, but I think that you can really only control the over/underscan from the mode timings and as you pointed out modelines are ignored in TVOut mode (have been for several versions of the driver I believe). I had a lot of difficulty getting 1080p working on my Samsung LCD without overscan in 50Hz using HDMI (not TVOut) - the only modeline that worked correctly had overscan, the correct mode timings caused the screen to have a heart attack. After a lot of messing around and threatening Samsung, they finally found me an option in the menu system that told it to "Just Scan" for the screen size (instead of 16:9 which I had selected by default) - this fixed it instantly - so perhaps a setting on your screen?
Edit: Just noticed in that readme file the xorg.conf option "TVOverScan" "<1.0-0.0>" option.... maybe try 0.0?

On the overscan issue. I worked around it by changing my TV setup. My TV, Hitachi P60X901, has two 16x9 options: 16x9standard1 & 16x9standard2. Switching to standard2 eliminated the overscan issue.

radmofo,
i also have a samsung (although a different model) and had pretty bad overscan problems. I found that there is a 'service mode' that allows many adjustments to be made to the picture that are not accessible using the normal menu.
for my TV, to enter the service menu start with the TV off then enter
Mute-1-8-2-Power
on the remote.
From there, you can play aruond with things like x and y axis adjustments, screen size and position etc...
hope it works for your TV as well.

hey All,
Well I just bought and dwnld'd the Sony 57" Service Manual for my set. Out of the box it set at 9% Overscan. Ouch. Although I do not mind getting my hands dirty at most of this stuff, the setting this things has are brutal so for instance there is not one general overscan adustment. I have 7 settings per gun - per mode - per input (scaling) - and they all have to be done to adjust the h - v sizes. There is a rough and fine adjustment for each of those as well. No wonder an ISF Cal cost upwards of 500$ around here.
So radmofo - be careful in your service menu - most if like the sony will not make any changes to the set unless written and saved to the NVM. So if you just power off nothing will be saved. Then you can go back in and try again, have a pen and lots of paper and right down everything you do or change.
If overscan adjustments are available on an earlier Nvidia carg like 7600GT etc. It would be almost worth picking one up tp try it out instead of paying big to have the set calibrated.
Regards,
Dave
I have a 7300 GT that wont allow any overscan changes at all. Thanks for the tip, I will be careful if I go in to "service" If I toast my TV this will be my last post after my wife gets a hold of me.
